Abstract

The utility model relates to a control device for group-controlling an elevator, which comprises a BITBUS or field bus network, a main controller, an elevator car controller, a floor controller displaying in the elevator car and a floor controller arranged in the elevator hoistway. The control device is characterized in that a induction module is further included, the induction module is accessed to the BITBUS or field bus network for judging whether the elevator hoistway has waiting passengers; the main controller is also used for judging whether giving instructions according to the signal of the induction module. The control device can reduce the unnecessary stopping of the elevator, improves the feelings of the customers and saves energy.

Description

The multiple control lift control setup

Technical field

The utility model relates to multiple control lift, relates in particular to the multiple control lift control setup.

Background technology

Present high-rise building generally all are provided with the multi-section elevator, are used to carry people or thing, and some building also is further divided into elevator elevator and Cargo Lift/passenger-goods lift.The general group control system that adopts manages and dispatches between the multi-section elevator, and group control system generally realizes based on BITBUS network system or fieldbus networks.In the prior art, in order to improve the efficient of elevator, the control of elevator is realized by group control system.When normal operation, group control system has good effect, but for the special moment, when for example going to work peak or next peak, perhaps a lot of people visit etc. to certain office building, single elevator will occur can't carry all clients, and other elevator do not run to the floor that client is waiting for, can prolong client's wait time, reduce the impression that client takes a lift.Fig. 1 is the elevator distribution schematic diagram of certain building, has four elevators at ground one deck, elevator 1, elevator 2, elevator 3 and elevator 4, and wherein elevator 1, elevator 2 and elevator 3 elevators, elevator 4 is passenger-goods lifts.Wherein elevator 3 and elevator 4 can arrive basement garage.Elevator 1, elevator 2 and elevator 3 elevators are by group control system control and scheduling parallel operation, elevator 4 independent operatings.Peak (for example peak of coming off duty) in the scattered using escalator of client, because elevator 4 independent operatings, and client can call out elevator 4, and the elevator 1 of parallel operation, elevator 2 and elevator 3, often the problem that occurs is, when Cargo Lift travels downwards, all to berth at a lot of floors, but do not have new passenger to enter Cargo Lift, cause energy dissipation, and the also non-constant of the impression of client's using escalator; For elevator 1, elevator 2 and the elevator 3 of parallel operation, also may appear at the passenger call elevator and leave escalator afterwards, cause unnecessary berthing.Certainly, the elevator for upwards moving unnecessary elevator also may occur and berth.

The utility model content

The utility model provides a kind of multiple control lift control setup, is used to solve the unnecessary problem of berthing of elevator.

The invention provides a kind of multiple control lift control setup, comprise BITBUS or fieldbus networks, master controller, elevator car, the floor controller that in car, shows and be installed on floor controller in the escalator,

Also comprise induction module, described induction module inserts described BITBUS or fieldbus networks, is used to judge whether escalator has the passenger who waits for using escalator;

Described master controller also is used for judging whether to send instruction according to the signal of induction module.

Described induction module comprises sensor and network access module.

Described network access module comprises embedded chip and network bridging chip, is used for the induction result of sensor is sent to master controller.

Described induction module is a sensor.

Described sensor inserts described BITBUS or fieldbus networks by the floor controller that is installed in the escalator.

Described sensor is the electrothermic type infrared pickoff.

Described electrothermic type infrared pickoff is pyroelectric infrared sensor or thermocouple.

Described instruction is for cancelling the instruction of berthing.

Described master controller is used for after the calling that responds the escalator passenger, indicates an elevator to this layer operation, if the signal judgement escalator that sends by induction module has not had the passenger, sends to this elevator and cancels the instruction of berthing.

The utility model can reduce unnecessary the berthing of elevator, improves the impression of client's using escalator, and saves the energy.

The specific embodiment

Below with reference to the accompanying drawings and embodiment, the utility model is elaborated:

Existing multiple control lift structure as shown in Figure 2, this elevator berths at n floor altogether, comprise elevator main controller, floor controller (car demonstration), elevator car, floor controller 1 ..., floor controller n.Elevator main controller mainly is responsible for control car position and operation, handle the various signals that each child node is beamed back, producing various control signals (comprises the communication signal with dragging system, controls the signal of each contactless switch and mail to the various control signals (child node is: each floor controller, elevator car etc.) of each child node.The floor controller is responsible for communicating by letter with master controller, upwards sends calling signal, and the receiving house following number of delivering a letter of beaming back, and finishes that calling signal is remembered, disannuled a call, floor and direction Presentation Function.The effect of elevator car mainly is that the interior signal that selects is reached elevator main controller.

Whether in order to solve the problem that the passenger waits for the using escalator overlong time, present embodiment is installed induction module at escalator, also have the passenger waiting in the escalator to judge; This induction module comprises sensor and network access module.A kind of structure of this induction module as shown in Figure 4, sensor is electrothermic type infrared pickoff (comprising pyroelectric infrared sensor and thermocouple), network access module is made of embedded chip and network bridging chip.After embedded chip installing operating system and the procotol, can communicate by network bridging chip and master controller.Induction module can be installed in each escalator, also can select to be installed in the bigger escalator of ridership (ground one deck escalator for example has the escalator in large conference room or dining room).Induction module inserts the BITBUS network, perhaps fieldbus networks, as shown in Figure 3.

In order to realize the purpose of this utility model, also the induction module that only comprises sensor can be inserted the floor controller, insert the BITBUS network by the floor controller, perhaps fieldbus networks, as shown in Figure 5.Master controller just can send control command according to the induction result of sensor and user's calling like this.

The result of the sensor induction has all passed through analog/digital conversion becomes digital signal, can be embedded into formula chip or floor controller and handle.

(if equidirectional and untreated this floor call sign that sends by elevator car not after master controller response escalator passenger's the calling, the then calling of master controller response stair case), send the instruction of berthing of current floor to elevator wherein, indicate it to stop ladder at this layer.At the elevator that is instructed in the process of passenger place floor operation, if master controller has not had the passenger by the signal discovery escalator that is sent of sensor, then send and cancel the instruction of berthing to the elevator of preparing to berth at this floor, cancellation stops ladder at this layer, and the floor that should berth to the next one moves.

Those skilled in the art can also carry out various modifications to above content under the condition that does not break away from the definite spirit and scope of the present utility model of claims.Therefore scope of the present utility model is not limited in above explanation, but determine by the scope of claims.
